swimsuit care
  • Hand wash in cold water as soon as you can after use (rinsing in the shower is fine!)
  • DO NOT machine wash.
  • Lay flat to dry, do not hang.
  • Do not dry clean, iron, or machine dry (even on a delicate cycle...) as this can, and most likely will, damage your onewith.
  • Hot tubs and chlorinated pools with harsh chemicals can impact the quality and longevity of any swimwear, so it’s best to avoid them if you want to keep your swim in tip-top shape.
  • If you wear your onewith under normal clothes, keep in mind that friction can create pilling/snagging. We prefer to wear our onewith under beach cover-ups/sarongs, which are created to be worn with swim.
  • Sunless tanners, suntan lotions, oils, and harsh chemicals can ruin your onewith - ensure to not get these products in contact with any swim/garments!

  • onewith = 2 layers of normal swimwear fabric, just like any other swimwear. people tend to think our swim is either 1 layer of fabric, and/or super thin, like no-show undies. that is not true! again, our swim has 2 layers of fabric. It's just bonded together, not sewn with tight seams, which gives it a sleeker appearance that people may read as "thin." While we can't guarantee our suits are frontal-wedgie-free, so-to-speak as every person's anatomy is different, we can say that there is no reason why our suits would cause 🐪toe more than any other swimwear.

  • yes, all of our bikini tops + one pieces have removable bust cups that you can leave in, or take out!

  • we get it, the itch to get your swim that doesn't dig in ASAP is real! luckily, we do offer an Express shipping option if you do need it ASAP. otherwise, we offer free standard shipping on US orders over $85. all orders with standard shipping ship from our Connecticut, USA warehouse within 2-5 business days of receiving your order.

  • ALL onewith suits feature our inner grip strip, which keeps the suits secure without the use of tight seams or elastic that digs. the inner grip strip is super soft and flexible.

    Good quality

    At first it was a bit tight and made it look like it was bulging but after stretching it a bit it conformed great to my body! I like how it doesn’t roll and stays put especially with the little elastic pieces to keep it in place. I’m excited to wear it to the beach :)

    No fear of accidentally slippage

    I wear a lot of similar bikini tops but the edges make it so the top doesn't move which helps prevent underwood from making an unwanted appearance when I am in the hot tub or pool.

    I love these bathing suits

    i’m wearing one as we speak. i love them the high waisted bottoms are gamer changers. they stay exactly where u want them to and they don’t move or fall down and they stretch like no other. my comfiest swimsuit (and i have some that are 160 for a top and bottom) i like these so much more. everyone has to give them a try!!
